FOR HORSESHOES.

SPECIFICATION forming part of Letters Patent No. 341,038, dated May 4.1886 Application filed January 12, 1885. Serial No. 152,561. (No model.)

To. all whom it may concern. 7

Be it known that I, IVILLIAM H. MILLER, of Cincinnati, Hamilton county,Ohio, have invented a new and useful Removable Oalk for Horseshoes, ofwhich the following is a specification.

My invention relates to an improved form of removable call: orsharpening attachment for horseshoes, as hereinafter particularlydescribed.

In the accompanying drawings, Figure 1 is an under side perspective viewof a sharpening attachment embodying myinvention, said attachment beingshown in place upon the horseshoe. Fig. 2 is an upper, and Fig. 3 anunder, side view of the members of my attachment separated from eachother and from the shoe. Fig. 4 is a transverse section of suchattachment in place upon the shoe.

A may represent a horses hoof, and B a customary horseshoe.

It is well known that in order to insure con tact exclusively at andnear the outer wall of the hoof it is the practice to chamfer both thehoof-sole and thetop of the shoe, so as to leave an interstice. I availmyself of thisinterstice to receive the points 0 of hooks or lugs O,that project at first upward and then outward from the tops of twosimilar curved plates, D D, from whose lower surfaces or soles projecttwo portions, E E, of a supplementary toe, e e, and two supplementaryheels, F F, all of which projections have sharp edges, as shown. One ofthese plates, D, has near its mid-length a square or other non-circularsocket, G, and the other plate, D, has a circular socket, G, for thecorresponding head, H, and point H of an expanding screw-bolt, I, whichcarries a nut, J. The said plates having been engaged with their hooksG, interposed between the hoof and the shoe at the inner or concave edgeof the latter, and the bolt I. having been insorted in the sockets G G,screwing of the nut J outward operates to press the said platesasunder,aud to cause their said hooks to firmly engage behind the shoe,as shown in Figs. 1 and 4, in which condition the call: or supplementaryshoe becomes for the time being an adjunct of the shoe proper.

My improved calk may be composed of any suitablematerial-such as steelor wrought or malleable iron-and is preferably plated with tin, for thedouble purpose of preventing rust and aflording a surface to which snowand ice will not adhere, which otherwise would be liable to ball theanimals foot.

I am aware that supplemental horseshoes consisting of two parts hingedtogether at their forward ends and having expanding-screws at their rearends are old, and such I do not claim.

I am also aware that supplemental horseshoes have been formed of twoseparate pieces of metal held upon the shoe proper by means of anexpanding screw placed at their midlength, and do not claim this,broadly, as my invention. In this device the two pieces which form thesupplemental shoe are bowed inward or toward the center of the foot, andonly bear upon the shoe at their extremities. This is objectionable, forthe reason that should a stone come against this inturned portion itwould most certainly wrench the whole shoe and foot very severely,thereby not only endangering the breaking or displacement of thesupplemental shoe, but also the loosening of the shoe proper.

= I am alsoaware that a supplemental shoe has been formed in twosections conterminous with the main shoe, articulated at their foremostextremities, and provided with an ex pandingbolt for holding them inplace.

I claim herein as new and of my invention- 1. The ealk or supplementaryhorseshoe consisting of the separate plates D D, conterminous with andbearing throughout their length upon the under surface of the shoeproper, having the lugs C, the toes e e, the heels F F, and the socketsG G, in combination with the nutted bolt or expander H H I J, located ator near the mid-length of the shoe, as and for the purpose designated.

2. The call; or supplementary horseshoe consisting of the separateplates D D, eonterminous with and bearing throughout their length uponthe shoe proper, having the up wardly and outwardly projecting lugs O cG c, with the sockets G G, formed in said lugs above the plane of theplates D, the toe-pieces e e, and the heel-pieces F F, in combinationwith the expander H I J, located at or near the mid-length of the shoeand above the plane of the plates D D, as set forth.

In testimony of which invention Iherennto set my hand.
